AppTrack Ninja MCP server

App Store and Google Play intelligence for AI assistants. Search and inspect any iOS app, read chart rankings, version history, in-app events, ads and publisher portfolios, see which icon and screenshot redesigns moved ranks, and manage your AppTrack Ninja keyword tracker from Claude, Cursor or any MCP client.

Full guide with every tool: apptrack.ninja/tools/mcp

This is a hosted remote server: there is nothing to install or run. This repository documents how to connect to it.

Get a key

Clients with OAuth (Claude, Claude Code, VS Code, Cursor, Windsurf, Codex, Gemini CLI) open the AppTrack Ninja sign-in on first use; no key needed. For other clients:

1. Sign in at apptrack.ninja (free plan works; Pro lifts the limits).

2. Open Account → MCP / IDE (direct link).

3. Create a key. It is shown once; keys start with ninja_.

Connect

Ask your AI agent

Agents that can edit their own configuration (Claude Code, Cursor, Codex, Windsurf) can add the server themselves. Paste this and replace the key:

Add the AppTrack Ninja MCP server to this tool.
Endpoint: https://mcp.apptrack.ninja (Streamable HTTP)
Send this header with every request: Authorization: Bearer ninja_your_key
Setup guide: https://apptrack.ninja/tools/mcp

Claude Code

claude mcp add --transport http --scope user apptrack https://mcp.apptrack.ninja
claude mcp login apptrack

With a key instead of sign-in:

claude mcp add --transport http --scope user apptrack https://mcp.apptrack.ninja --header "Authorization: Bearer ninja_your_key"

Cursor

~/.cursor/mcp.json, or .cursor/mcp.json in a project:

{
  "mcpServers": {
    "apptrack": {
      "url": "https://mcp.apptrack.ninja",
      "headers": { "Authorization": "Bearer ninja_your_key" }
    }
  }
}

VS Code (GitHub Copilot)

.vscode/mcp.json in your workspace:

{
  "servers": {
    "apptrack": {
      "type": "http",
      "url": "https://mcp.apptrack.ninja",
      "headers": { "Authorization": "Bearer ninja_your_key" }
    }
  }
}

Other clients

Any client that supports remote MCP servers with custom headers:

• URL: https://mcp.apptrack.ninja

• Transport: Streamable HTTP

• Header: Authorization: Bearer ninja_your_key. Gateways that reserve Authorization can send the key in X-Api-Key instead.

Claude Desktop and claude.ai custom connectors: add https://mcp.apptrack.ninja as a custom connector and sign in with AppTrack Ninja when asked (OAuth).

Tools

Every tool except the two tracker writes only reads AppTrack Ninja's stored data; nothing removes or overwrites anything.

On the free plan list tools return up to 10 rows and, once the 25 daily calls are used, answer with an upgrade note until the next UTC day.

Example prompts

• "What are the top grossing games in Japan right now?"

• "Show me the apps published by Duolingo and their ratings."

• "Which icon and screenshot redesigns lifted chart ranks in the US this month?"

• "Show the release notes of Notion's last five versions."

• "Compare Block Blast! on the App Store and Google Play."

• "Track the keywords 'pdf scanner' and 'scan to pdf' for my app 6736992829, then show their current ranks."
